CH3352 Fluid Mechanics for Chemical Engineers Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES:

 To enable the students to acquire a sound knowledge on fluid properties, fluid statics, dynamic characteristics of fluid flow for through pipes and porous medium, flow measurement and fluid machineries

UNIT I

Methods of analysis and description – fluid as a continuum – Velocity and stress field – Newtonian and non-Newtonian fluids – Classification of fluid motion

UNIT II

Fluid statics – basic equation – equilibrium of fluid element – pressure variation in a static fluid – application to manometer – Differential analysis of fluid motion – continuity, equation of motions, Bernoulli equation and Navier- Stokes equation.

UNIT III

The principle of dimensional homogeneity – dimensional analysis, Rayleigh method and the Pitheorem – non-dimensional action of the basic equations – similitude – relationship between dimensional analysis and similitude – use of dimensional analysis for scale up studies

UNIT IV

Reynolds number regimes, internal flow – flow through pipes – pressure drop under laminar and turbulent flow conditions – major and minor losses; Line sizing; External flows – boundary layer concepts, boundary layer thickness under laminar and turbulent flow conditions- Flow over a sphere – friction and pressure drag – flow through fixed and fluidized beds.

UNIT V

Flow measurement – Constant and variable head meters; Velocity measurement techniques; Types, characteristics and sizing of valves; Classification, performance characteristics and sizing of pumps, compressors and fans

TOTAL: 45 PERIODS

OUTCOME OUTCOMES:

On completion of the course, the students would be able to
 Understand the fundamental properties of fluids, stress-strain relationship in fluids, and its characteristics under static conditions and establish force balance in static systems.
 Apply Bernouli principle, Navier – Stokes equation and compute pressure variation in static fluid.
 Use of dimensional analysis to derive relationships among process or system variables. Further they would develop dimensionless groups that help in scale-up studies.
 Understand the different types of flow conditions in fixed bed and fluidized beds.
 Describe function of flow metering devices, apply Bernoulli equation to determine the performance of flow-metering devices and also analyze the performance aspects of fluid machinery such as pumps, compressors and valves.
